Let's divide 66202553 by 166
We want to divide 66202553 by 166.

Step 1:
The number 166 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 166

Let's proceed to step 2:
If we divide 66 by 166, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (2) from the dividend, add it to 66, then carry on: 662 / 166

Step 3:
The number 166 fits into 662 3 times, leaving a remainder of 164.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 164 after subtracting 498 from 662.
Grab the next digit (0) from the dividend, add it to 164, then carry on: 1640 / 166

Let's proceed to step 4:
When dividing 1640 by 166, we get 9 with a remainder of 146.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 1494 away from 1640, we end up with 146.
Fetch the next digit (2) from the dividend, attach it to 146 and continue: 1462 / 166

Let's proceed to step 5:
If we divide 1462 by 166, we get 8 and a remainder of 134.
Write down 8 as next digit of the result. 
Result so far: 398.0
Subtracting 1328 from 1462 leaves us with 134.
Fetch the next digit (5) from the dividend, attach it to 134 and continue: 1345 / 166

On to step 6:
If we divide 1345 by 166, we get 8 and a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 3988.0
Deduct 1328 from 1345 and we're left with 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 166

Advancing to step 7:
166 goes into 175 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 39881.0
If we subtract 166 from 175, we get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 166

Let's proceed to step 8:
When dividing 93 by 166, we get 0 with a remainder of 93.
Record the quotient 0 as the next digit in the result. 
Result so far: 398810.0
Subtracting 0 from 93 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 9:
When dividing 930 by 166, we get 5 with a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 398810.5
Subtract 830 from 930 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
If we divide 1000 by 166, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 398810.56
Subtract 996 from 1000 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
166 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 398810.56
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
166 can be fit into 400 2 times, resulting in a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 398810.5602
If we take 332 away from 400, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
166 goes into 680 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 398810.56024
If we take 664 away from 680, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
160 divided by 166 is 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 398810.56024
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
1600 divided by 166 is 9 with a remainder of 106.
The next digit of our result is 9. 
Result so far: 398810.5602409
If we subtract 1494 from 1600, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 16:
166 goes into 1060 6 times with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 398810.56024096
If we subtract 996 from 1060, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 398810.56024096, and the remainder is 6.4e-08.
